A lot of core gamers don't like these changes, though. Look what's happened to WoW. It's super accessible for casual players to see all the content, but it makes the content feel cheapened to core gamers. Sure, they did it on a more difficult setting, but if the rewards aren't commisserant, then it doesn't feel as good. Hardcore gamers want to feel exclusive and set apart by their skill and accomplishments, and then they want to brag about it. If 80% of the server has the achievement for completing the final raid and it's the same achievement on every difficulty level, they feel cheated. Hardcore gamers also don't want to pay huge amounts for a game, so devs are forced to make content for more people to bring in more money.
I think Carbine is making a lot of right moves; it remains to be seen how well it plays out and is received.
As I stated above, they are trying to find the middle ground. WoW did exactly this. They said:"We have all this wonderful content, but only 1% get´s to see it, this must change."
It would have been smart, to make the Raidfinder sets look ugly and only the hardmode sets to look awesome, this would already help a lot.
About Carbine, they are trying hard to keep it accessible, but train people as they play. This is a great idea, we will have to see how good it holds up.
